2. Dugald's parents Dugald McGregor and Catherine McColl

I don't have much proof that these are Dugald's parents, other than they are about the only pair in the records that are the correct age and match the names given to his children - 1st son after his father and 2nd daughter after his mother. Another possibility is John and Catherine
